and useful Improvement in Pattern Mech anism' for Knitting-Machines, of whichthe following is a full, clear, and exact .descrip--- tion,--'referenc.e being had. to the accompan ing-drawings,.which form a partof this speci- 'fioatlonp My invention has f or its object certainiinprovements in pattern mechanisms for kn1t tin'g' machines, I. especially adapted for the purposeof contro ling or -moving the cam everto varyingr'heights to control the move ment in and out of operation of a lurality of thread carriers, shown and described in Let ters Patent No. 640,769, issued to me Jan-11 In that patent the rod orary 9th, 1900. lever controlling the thread carriers controlling cam is lifted to varfing heights by means of plates of varying heights, secured to the surface of a Wheel or drum, but tl' pattern mechanism enables only a limited-Nana tion of the combination of thread carriers.

My present invention has for its object a pattern mechanism which will have the capac ty t'o v'ary the combination of thfizad" carriers used'toan unlimited extent.

I will first describe the embodiment of my invention, illustrated in the accompanying dra'win s, and then point out the invention in the 0 aims.

In the drawings, will only illustrate that portion of the machine shown and described in InyPatent N 0. 640,7 69, as is necessary to an understandingof the present, invention and will omit such er partsasare shown and described in t atent. In the drawings a portion of a knitting machine.

act with the different rollers and their col re flponding levers, and thread'carriersfall as. escrib'ed' in said Patent No. 640,769..

The cams E and E, as in Patent No. Q

640,769, are'secured to a block E, supported upon the rod-E, which is ca able of vertical helow'erlend of" movement in guides 6 a this rod rests uponthe. end of theflevjer E pivoted at e to the" frame of the machine. Connected to this lever between its pivot: point and the rod E is-the projection e O is a wheel supported so as to revolve.-

This .Wheel has on each side'the sprocket teeth 0.

G are a plurality of blocks having inclined upper'cam faces and said blocks are of different heights. Each block, at one portion of its end, has asocket g. and at another pn-rtion an orificed rojeotion 'gcorresponding-to the hey are associate portions of contiguous projections. "These olts have at one end an enlarged head it and a threaded o posite end h. on Whichfworks a threaded ho ding nut h corresponding to head 72 Both thez end of head hand holding nut h have the inset or cut it onefor a hold-f ing, the other for a turning device, "By this arrangement can form aattern device provided with. PIOJGCtlIlg b ocks ,and arrange themin any desired relation, number and way with each other, orany desired number with relation to each other. The head and nut of the bolt enter between the sproc-rklet 1e t g ther-bye. bolt assin throu h corres 'ondin orificed P g g P s 75 blocks projcting'beloiv the bolts rest upon the wheel between the sets of sprocket teeth before the bolts bottom in thesprocketteeth,

By this construction, the blocks have a positive and fixed seat on the wheel, while the bolts, as it were, float between the sprocket. teeth. i The projections rests upon the surface formed by the blocks G and depemlent upon the height'of block immediately acting upon the projection e depends the position of cams E and E. By the use of a pattern device ofthis kind and properly associating the blocks used I can proiluce all the possible sequence or order-of associationof action of the thread carricrs :md'I-can also provide for any numher of duplications of any given sequence. Tho wheel .0 is rotated mtcrm'itlcntlv ll) This rocking lever is constructed as, and

{rocked in the manner,- set out in m Patent operate chain E".

No,[,640,769 Pivotcd to the lever B are the two pawls e and e". The pawl e works in the ratchet E secured upon the shaft to Thepawl 0". works inthe ratchet E", connected to wheel E This pawl is held out of action in the following manner: e is a rock-shaft having the sprin e". U on this shaft are the levers e"- an e". T e outer end of lever e" rests against a pin e upon the pawl e" and, by the action of the sprin" e, holds said pawl out of enga ement with the teeth of ratchet'E". The e ver e is in alinelnent withprojections e upon the chain E", and when struck-by said projection, the shaft e is rocked, causing 1ever e. to be depressed, allowing the awl e" to eng e the teeth and move the w eel, When t e wheel C is thus revolved, the

, sprocket teeth 0, through the medium of the bolts, pull the pattern device, composed of the blocks, around with it.

cific purpose oruse of my invention hereinbefore set forth, as the same is ca able of use for other purposes and I inten to include aving now fully described my invention,

' connecting I do not intend tolimit'myse1f to the spe' what I claim and desire to protect by Letters I Patent isv 1. The combination of a toothed Wheel, a chain formed of cam blocks, flexibly connect ed by connecting members, the blocks in the movement of the chain resting upon the face of the wheel and the connecting members floatling between and being moved by the teet 1.

2. The combination with a toothed driving wheel, of a pattern link chain, the links being supported u on the faceof the wheel and the ink members floating between the teeth of the Wheel.

3. In combination, with a wheel having two sets of circumferential pro'eoting teeth, of a plurality of blocks, bolts exibly securing said blocks together, there being a portion of said blocks beneath said bolts, the bolts floating between contiguous projecting teeth andthe blocks resting on the wheel be tween the sets of teeth.

In testimony of which invention, I have hereunto set 111 hand, at Philadelphia, on this 19th day 0 January, 1905.
